Numerical Analysis of DNA Earth Penetrator Experiment at DRES

Abstract

A finite difference Lagrangian code calculation for the firing of an earth penetrator into a soft soil site has been carried out. The penetrator was a 400-lb, 6.5-in. diameter steel projectile with an initial velocity of 500 ft/ sec. The field tests were conducted in July 1974 at the DRES Site in Canada. The penetrator was treated as a ridig body in the code solution. A four-layer idealization of the target site was used.
